Fans that are used to pressurize a space or create mechanical air pressure in a system are referred to as forced draft fans. Occasionally, manufacturing spaces are required by specifications to be maintained at a specific positive pressure. This requirement is common in clean room processes for scientific work. Forced draft is also used to identify the combustion process used in large boilers. When mechanical ventilation is supplied to these boilers, the heat transfer rate increases; the boiler can be reduced in size to produce the same amount of energy as natural draft.

The New York Blower Company offers literally thousands of different types, models and sizes of air-movement equipment that can be customized and tailored to your specific application. See the chart below for a list of recommended fan designs, materials and features for forced draft use, or contact us to request a quote.
